I just stumbled on a Google violence map:

Most of the crime has of course been in Ferguson...but if you fish around you can find a few malls that were closed for a few hours, that are a good distance away.
Most ominous - the yellow ‘envelope’ symbols are where Community Organizing type activities have occurred - vigils, meetings, etc....and that is spread all over the area, to include downtown.
The malls must be accessible by mass transit; poor planning...
